Answer:
Step-by-step explanation:
110 * x/100 = 100 Multiply both sides by 100
110 * x = 100*100 Combine the right.
110 * x = 10000 Divide by 110
x = 10000/110
x = 90.9 %
But that is not the answer you want. It is asking by what % if 100 smaller than 110
The answer is 100 - 90.9 = 9.09
So if you take 9.09 /100 * 110 you should get the number that you subtract from 110 to get 100.
